ios - 在集合视图单元格中设置文本时出错

Question

当我将它设置为NULL后nslog值时，为什么？

CustomCollectionVIewCell *cell =[[CustomCollectionVIewCell alloc]init];
NSString *name =[dict valueForKey:@"filterName"];//works
[cell.labelDisplay setText:name];//does not
NSLog(@"name = %@",cell.labelDisplay.text);
cell.isSelected=NO;
[_availableHealthFilters setObject:cell atIndexedSubscript:i];

在自定义单元格中初始化您的 labelDisplay。

//customColectionCell.h
@property(strong,nonomatic) NSString *labelText;
-(void)setCellLabelText:(NSString *)labelText;
//customCollectionCell.m
-(id)init{
//init cellLabel and addSubView to customCell 

}
//Than set label in custom method
-(void)setCellLabelText:(NSString *)labelText{
_labelText = labelText;
sefl.labelDisplay.text = labelText;
}
